The times, they are a-changing for Barry Allen. After he stopped his mother's murder in "The Flash" Season 2 finale, he found himself in an all-new timeline that only he knows about -- but apparently, he won't be aware of that for much longer when Season 3 picks up.
"In the same sense that he's forgetting a lot of memories, it means he's forgetting his powers too," Grant Gustin told DC All Access. "It's like he's having a full 'Back to the Future' moment, where essentially his hand is disappearing in front of him."
"Barry is the only one that knows the timeline is different, and his memories are starting to get replaced from the previous timeline with new memories, like graduating high school and graduating college, moments with his family," he explained. "When he realizes those memories are replacing other memories, that's when he stars to realize how selfish of a decision this was and that maybe he should try to put things back the way they were."
Keiynan Lonsdale, who plays Wally West, also weighed in on the importance of his character to "Flashpoint." "Kid Flash is a big part of 'Flashpoint,'" he shared.
"Wally is definitely in Joe's life," added Jesse L. Martin. "He's definitely Joe's son, but Wally's got a life that Joe knows nothing about."
